I am facing problems with debugging DomU. I have made changes in the gdt table in the file head.S for Dom U. Because of that the domain is crashing. For debugging, I followed the steps mentioned in the file /xen-unstable/tools/debugger/gdb/README. I also made changes in the /xen/Rules.mk file and compiled domU with -g C flag. However, as mentioned in the README file no /var/xen/dump/<Domain-name>.<DomainID>.core file is generated. Rules.mk file : verbose ?= y debug ?= y perfc ?= n perfc_arrays?= n domu_debug ?= y crash_debug ?= y Am I missing something? Thanks for replies. -Purav _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
domu_debug and crash_debug are mutually exclusive.

With the patches I've sent today domu_debug is now a run-time option.
Enabling crash_debug will not interfere with domU debugging.
